The 31-year-old missed United's last two games with what Jose Mourinho described as a 'small muscular injury'.

Rooney was an unused substitute for the 2-0 win over Watford a fortnight ago after being ruled out of the trip to Leicester with illness. He last featured as a second-half substitute during the draw with Hull on February 1.

Speaking after the 2-1 win over Blackburn on Sunday, Mourinho revealed he did not expect Rooney to be fit for the Europa League last-32 second leg with St Etienne on Wednesday. He also raised doubts about whether the striker would be fit for the EFL Cup final with Southampton at Wembley on Sunday.

But Rooney was involved in training at Carrington on Tuesday morning as United prepared for their trip to France. Phil Jones, who has been absent for the last four games with a bruised foot, is still sidelined.

United trained at Carrington on Tuesday morning.

Rooney was part of a group of 10 players who trained separately from the others along with Matteo Darmian, Chris Smalling, Marcos Rojo, Ashley Young, Michael Carrick, Anthony Martial, Jesse Lingard, Henrikh Mkhitaryan and Marcus Rashford.

David De Gea took part after the Spaniard was rested for the FA Cup tie at Ewood Park at the weekend. Ander Herrera was missing from the session. The midfielder will miss the game in St Etienne through suspension.
